 SOIL FROM MR BOWIE, MAINS OF KELLY. 



A remarkably light-coloured soil. When dry, its colour is that 

 of a very pale guano ; and the subsoil is even lighter in tint. 

 When moist, they are of course darker, but still only a mode- 

 rate brown. They contain some very hard silicious stones, which 

 are all more or less water-worn.
